Birds love it. Squirrels don't! This bird seed is infused with the natural oil of hot peppers. Birds can't taste or notice the hot pepper, but mammals such as squirrels will definitely taste the heat and will tend to look elsewhere for food once they've tasted the fiery heat of the peppers! Contains sunflower hearts, peanuts, golden safflower, mealworms and capsaicin... oh and it is extra spicy hot! This product contains a strong eye, nose and skin irritant (hot pepper). Wash hands thoroughly with soap and water after handling and keep out of reach of children.
